Vacuum Casting Rapid Prototyping Of Small Production Runs For ABS
Polyurethanes
Vacuum Casting :
Vacuum casting is a swift, budget-friendly method for replicating
top-notch plastic parts, akin to injection-molded items. It employs
dual-component polyurethanes and silicone molds crafted from a
3D-printed prototype. This approach is ideal for testing fit and
function, marketing needs, or producing limited runs of final-use
components.
Industries involved:
Robotics,UAVS(unmanned aerial vehicle),Medical equipments,Plastic
enclosure,Eletrical products,Phone case,auto parts,Household
appliances,Sporting equipments,Military,etc.
Benefits Of Vacuum Casting
Vacuum casting offers efficient manufacturing of intricate shapes
with high precision, cost-effectiveness, and versatility:
- Easily create complex shapes with precision.
- Simultaneously produce multiple components for enhanced efficiency.
- Rapidly prototype using quality urethane for small batches.
- Diverse material properties with different polyurethanes.
- Economical manufacturing due to low polyurethane costs.
- Efficient silicone mold production compared to metal molds.
Urethane Casting Tolerance Guidelines:
| Maximum build dimensions | The size of the mold is limited by the dimensions of the vacuum
chamber (1,900 x 900 x 750 mm) and by the volume of the product
(maximum volume: 10 liters). |
| Standard accuracy | ±0.3% (with a lower limit on ±0.3 mm on dimensions smaller than 100
mm). |
| Minimum wall thickness | At least 0.75 mm to ensure the mold is filled properly; for best
results, wall thickness of at least 1.5 mm is recommended. |
| Surface structure | High-quality surface finish comparable to injection molding. |

Vacuum Casting Process
Creating polyurethane vacuum cast parts involves three main steps:
master pattern creation,
mold fabrication, and part casting.
1. Master Pattern Creation:
Crafting patterns from your CAD designs is the initial step. These
3D solids are made through CNC machining or 3D plastic printing
like SLA/SLS. You can provide patterns or let us create them.
Patterns should endure up to 50°C heat.
2. Mold Fabrication:
Liquid silicone forms the casting molds. It's poured around the
master pattern within a casting box, cured in an oven for 15 hours.
Afterward, the mold is opened, and the master pattern is removed,
yielding a negative cavity mirroring the original. Our silicone molds typically yield around 25 copies of the master
pattern.

FAQ:
- Why would you choose vacuum casting over 3D Printing?
Choosing vacuum casting over 3D printing hinges primarily on
material quality and performance.
Vacuum casting offers superior materials that closely replicate
those found in commercial products.
If material performance and product aesthetics are paramount, opt
for vacuum casting.
- What industries are using vacuum casting?
As vacuum casting can be used for low volume production as well as
mass production, it is applied by various industries such as
consumer products, food and beverage, electronics, and etc.
- Can I make production-quality parts using vacuum casting?
Vacuum casting is best for making visually impressive prototypes,
but it can also be used for non-mechanical end-use parts.
